The Karnofsky prognostication scale is most appropriately used to screen patients with which medical diagnoses?

Correct Answer: D

Rationale: The Karnofsky Prognostication Scale is commonly used in patients with terminal illness, such as AIDS, to assess their functional status and predict their prognosis. Patients with AIDS often experience rapid decline in health, making this scale useful in determining their overall well-being and potential outcomes. Incorrect choices: A: Respiratory diseases - The Karnofsky scale is not commonly used for screening patients with respiratory diseases. B: Cancers - While the Karnofsky scale can be used for cancer patients, it is most commonly associated with terminal illnesses like AIDS. C: Cardiac diseases - The Karnofsky scale is not typically used for screening patients with cardiac diseases.

Correct Answer: B

Rationale: The correct answer is B because distributing nondocumented information about gender-based performance evaluations violates the National Labor Relations Act, which prohibits making false statements about an employer. This action could potentially mislead employees and interfere with the election process. Choices A, C, and D are not prohibited actions by the National Labor Relations Board. Choice A involves a legal and common method of gauging interest in unionization. Choice C involves providing information about union benefits and grievances, which is a protected activity. Choice D is permissible as long as it does not contain false or coercive statements.

Correct Answer: D

Rationale: The correct answer is D because informed consent requires the registered nurse (RN) to communicate all necessary information to the patient so they can make an informed decision. This includes explaining the procedure, potential risks, benefits, alternatives, and any other pertinent information. The RN plays a crucial role in ensuring that the patient understands the information provided before giving consent. Choices A, B, and C are incorrect because informed consent is not solely mandated by federal law, must disclose risks as well as benefits, and should not involve concealing any known risks.

Correct Answer: D

Rationale: The correct answer is D: Biofeedback. Biofeedback is a type of CAM that involves using electronic devices to help individuals gain awareness and control over physiological processes, such as heart rate and muscle tension. In this case, the older adult is using imagery as a form of biofeedback to alter the dysrhythmia. Ayurveda (A) and Dosha (B) are traditional Indian systems of medicine based on balancing bodily energies, not directly related to using imagery for heart rhythm control. Homeopathy (C) is a system of alternative medicine based on the concept that "like cures like" and uses highly diluted substances, not imagery or biofeedback techniques.

Correct Answer: C

Rationale: The correct answer is C: Ask to observe the skill as it is being performed; then perform it under direct supervision. This approach allows the novice nurse to learn through observation and hands-on practice under direct supervision, ensuring proper technique and safety. By observing the skill first, the nurse can understand the correct steps and potential challenges. Performing the skill under supervision provides real-time feedback and guidance. This method promotes active learning and confidence-building. Rationale for incorrect choices: A: Reading the procedure manual is helpful but may not provide the necessary hands-on experience and immediate feedback required for skill acquisition. B: Practicing in a skills laboratory can be beneficial, but it may not offer the opportunity for direct supervision and feedback from experienced professionals. D: Trying to remember from a previous simulation may not be reliable and lacks the real-time guidance and correction needed for skill mastery.

Correct Answer: B

Rationale: The correct answer is B: CAM consumers want personalized health care. This is because CAM focuses on holistic and individualized approaches to health, addressing not just symptoms but underlying causes. Consumers seek CAM for tailored treatments and a more patient-centered approach. Choice A is incorrect because CAM often involves practitioners who may not be traditional physicians. Choice C is incorrect as quality of life, rather than just quantity, is increasingly valued in Western society. Choice D is incorrect because although there is some evidence supporting CAM, it is not always readily accessible or universally accepted.

Correct Answer: C

Rationale: The correct answer is C because it encourages the patient to provide detailed information and express themselves freely. By asking the patient to "Tell me what day of the week today is," the nurse is prompting an open-ended response, allowing the patient to share their understanding. Choice A is closed-ended, requiring a simple yes/no answer. Choice B is slightly better as it prompts for information, but it is still closed-ended. Choice D is irrelevant to the question of determining cognitive function and history. In summary, C promotes open communication by encouraging the patient to elaborate, while the other choices limit the patient's response.

Correct Answer: A

Rationale: The correct answer is A: deployment flowchart. A deployment flowchart is a visual representation that outlines the steps involved in a specific process, making it ideal for the nurse to follow when administering medication at the vastus lateralis site. It provides a detailed, step-by-step guide, ensuring the process is carried out accurately and safely. Explanation of other choices: B: Top-down flowchart - This type of flowchart shows the hierarchy or sequence of steps in a process but may not provide the specific details needed for the nurse's task. C: Pareto chart - A Pareto chart is used to prioritize and identify the most significant factors in a process, not suitable for providing step-by-step instructions. D: Control plot - This term is not related to providing detailed instructions for a process, making it an incorrect choice.

Correct Answer: B

Rationale: The correct answer is B: functional nursing. In functional nursing, tasks are divided among different levels of nursing staff based on their skills and qualifications. This system is task-oriented, with each staff member responsible for a specific function, such as medication administration or personal hygiene, for the entire unit. This allows for efficient and specialized care delivery. A: Total patient care involves one nurse providing all aspects of care to a group of patients. C: Team nursing involves a team of healthcare professionals working collaboratively to provide care to a group of patients. D: Primary nursing assigns one nurse to oversee the care of a group of patients from admission to discharge.
